One Degree

One Degree is a California-based 501(c)(3) nonprofit technology organization that empowers low-income and underserved individuals, families, and social-service professionals to find and access life-changing benefits and services. Its Resource Server API exposes a curated, community- maintained database of social-service resources — organizations and the opportunities (programs and services) they offer, along with locations, phones, schedules, ratings, tags, comments, images, properties, guides, and housing properties. The API is designed for interoperability with third-party services so communities can coordinate and deliver social services more effectively. It is a read-focused REST API served at data.1degree.org/v1, authenticated with an api_key query parameter and HMAC-SHA256 request signatures for write verbs. Resource data is licensed under Creative Commons Attribution-NonCommercial 4.0 International.

One Degree publishes 6 APIs on the APIs.io network, including Housing API, Locations API, Opportunities API, and 3 more. Tagged areas include Company, Nonprofit, Social Services, Community Resources, and Human Services.

One Degree’s developer surface includes documentation, API reference, engineering blog, support, signup flow, authentication, and 16 more developer resources.
